HYDRQCARBON INCANDE SCENT LAMP.

SPECIFICATION forming part-of Letters Patent No. 760,671, dated May 24,1904.

Application filed November 30, 1898. Serial No- 697,892. (No model.)

To all whom it may concern:

Be it. known that I, GEORGE WASHINGTON,

of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Hydrocarbon Incandescent Lamps; and I do hereby declare the following to be a full, clear, and exact desc'rip tion'of' the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My lnvention relates to an improvement 1n hydrocarbon incandescent-lamps; and it consists in the parts. and combinations of parts and in details of construction, as will be more fully described and pointed out in'the claims.

In theaccompanying drawings, Figure l' 'is a View in sectlon of a lamp embodying my invention. Fig. 2 is a view in section on the hue m w of Fig. 1. Flg, 3 1s a view of the vaporizer, and Figs. 4, 5, 6, 7, 8,"9,'10, 11, and 12 are views in section of modifications.

D represents a burner provided with a depending cylindrical base Q, constituting the commingling chamber, where the air and vapor' generated are commingled. This commingling-chamber is closed at its bottom and is provided at a point near its bottom with an "por is controlled or regulated by the collar and size with the air-inlet opening M in com 'or valve L, mounted on the lower end of the commingling-chamber Q and providedwith.

an opening corresponding in'shape, position,

mingling-chamber; By turning this valve to cut off more orless of the airthe quantity of air supplied to the commingling-chamber can be regulated --to a nicety. I

Located alongside of the comminglingchamber Q and adjacent'to the base of the burner D is the auxiliary burner I, adapted to heat the vaporizing-coil A and vaporize the oil therein. This burner is provided with a perforated cap J, located slightly above the open lower end of the body of the burner and is connected to the commingling-tube by I passing 'to the auxiliary burner burns down-- wardly in contact with the coil of the vaporizing-pipe A. This pipe A is made of thin metal, so that the oil therein may be vaporized by a match, taper; or torch and is provided, preferably, with a coupling 0, by which it'is removably secured to the supply-pipe P. This vaporizing-pipe is bent. in the form of a cylindrical coil, as shownfthe upper end of which rests within the open end of the body ofthe auxiliary" burner I, while the free end of the pipe after passing downwardly within the coil is bent at right angles and terminates j within thecommingling-chamber Q, near the base thereof, and is provided on its upper face near its free end with a jet-orifice B, which latter is preferably located approximately in the vertical center of the commingling-chamber.

is minute in diameter and of thin'metal, the

vapor-issues from the jet-nozzle in the vaporizing-pipeand rising draws in air, and part of the 7 mixed air and vaporpasses into the auxiliary burner I and coming in contact with the flame from the match,taper,or torch used for the ini-' tial vaporization of the oil becomes ignited and continues the vaporization so long as any vapor is permittedto escape into the comminglingtube Q from the vaporizing-tube 'A. Thus it will be seen that by cutting off partly the supply of oil to the vaporizing-tube or the supply of vapor to the commingling-tube a sufficient heat can be maintained at the auxiliary burner for continuing the vaporization of oil therein and sufficient for maintaining a pilot-flame at the main burner, so that the lamp may be ready for instant use after it has been once started by simply increasing the oil or vapor supply, as the case may be. The vaporizing-tube coiled, as shown, is liable to clog and would be diffieult to clean; but it is purposely made of cheap inexpensive material and is removably secured in place, so that it may readily be removed and replaced by another when it becomes impaired by reason of the deposit of carbon on the inside thereof.

The burner thus constructed may be attached toan' ordinary hand-lamp having connections for attaching an air-pump for compressing the air therein or it may be permanently attached to a bracket and provided with an oilsupply pipe leading to a suitable supply of oil under pressure or suitably elevated to flow by gravity to the lamp or lamps.

In the construction shown in Fig. 4 I have continued the auxiliary burner I downwardly within the coil, as shown, and instead of using aperforated burner-cap, as in Fig. 1, have perforated the side of the auxiliary burner, thus bringing the several jets into contact with the coil throughout the entire length thereof. Again, the pipe H instead of being of U shape, as shown in Fig. .1, is straight and provided at its inner end with an angular elbow 0, opening downwardly.

In Fig. 5 I have arranged the vaporizingeoil horizontally instead of vertically and employ a straight horizontal auxiliary burner I centrally within the vaporizing-coil. This burner-tube I is perforated on all sides, so as to heat the entire coil, and the burner preferably carries an alcohol-cup I for the initial heating of the vaporizer.

In Fig. 6 the vaporizing-coil is shown located above the burner, and I may instead of using a coil employ a straight vaporizing-tube, as shown in dotted lines.

If desired, I may locate a vaporizing-coil around the commingling-chamber Q and below the main burner, as shown in Fig. 7. In this construction the auxiliary burner I is formed in the base of the main burner or around the top of the commingling-tube Q, and the flames therefrom impinge against the top of the vaporizing-coil A which in the present instance is of greater diameter than the vaporizer previously described. In this device mixed air and vapor are conducted to the auxiliary burner by the pipe J, cut away on its lower side for the free passage of the vapor to the burner, and a starting-cup I, carried by the commingling-tube, is preferably employed for starting the vaporization of the oil.

Fig. 8 dicloses a construction identical with thatdisclosed in Fig. 6, except that the burnerflames from the auxiliary burner issue from the sides instead of from the bottom of the burner I and impinge against a single vaporizing-coil A, surrounding the auxiliary burner.

In the construction shown in Fig. 9 I have provided a cylinder or shell T, surrounding the commingling-chamber and constituting an elongated auxiliary burner T. This casing or shell T is closed at its lower end, and the combined vapor and air entering the auxiliary burner through the pipe J at or near the upper end thereof descends and burns at or near the lower end and against the vaporizing-coils A located adjacent to the lower end.

In the construction shown in Fig. 10 I employ the same shape and construction of auxiliary burner as shown in Fig. 8; but instead of employing vapor-escape orifices in the side of the burner, as shown in Fig. 8, I have provided a horizontal burner-pipe I, perforated on its lower side and resting immediately above the vaporizer-tube J which in the present instance is a straight tube, and have also shown a starting-cup I, carried by the oil-supply pipe P and located immediately below the vaporizer.

Fig. 11 discloses a structure having the principal features of the construction disclosed in Fig. 7. Instead, however, of having a straight commingling-tube, as shown in Fig. 7, the commingling-tube is U shape and open at its outer end, and the vaporizer-tube A passes horizontally from the coil and discharges downwardly into the commingling-tube Q. In this device I have shown the comminglingtube provided with a screw-boss V for its attachment to a lamp-post or wall-bracket and have also shown a bracket V, connected directly to the outer member of the commingling-tube for its attachment to a wall. Either of these devices for supporting the lamp may be employed, or I may use any other form, as these attachments are intended simply as suggestions as to the manner of supporting the burner.

It is evident that instead of discharging the vapor downwardly, as in Fig. 11, it could be discharged horizontally into a comminglingchamber shaped as shown in Fig. 12.

In Fig. 13 I have shown a construction designed for a plurality of main burners, and it comprises a body W, having in the present instance two main burners D, each having a mantle. This body is preferably cylindrical in shape and horizontal, as shown, and is provided near its bottom or lower side with the commingling tube Q This tube passes through the head at one end of the body and is open for the free passage of the vapor and air, and its other end, which is also open, terminates within the body W and discharges the mixed air and vapor therein. The auxiliary burner W" comprises simply an angular pipe at, the inner end of which is located within the commingling-tube and opens forwardly or toward the jet-orifice B in the vaporizer-tube,

so that a portion of the mixed air and vapor passes therein and is burned in contact with the vaporizing-tube, which latter is located immediately under the auxiliary burner W 5 The vaporizing-tube is bent upwardly at its end adjacent to theopen end of the commingling-tube and is provided with a vapor-escape orifice B in line with the open end of the commingling-tube.

In the construction shown in Fig. 1 I have provided a needle-valve Y for regulating the supply of vapor. The shank Y of this valve passes through a sleeve Y where it is held by frictional contact. Hence it will be seen that by adjusting the valve the escape of vapor may be regulated and controlled and the friction-sleeve may be carried by the vaporizing-tube or by the commingling-tube; but I prefer to attach it to the tube.

While I have not shown the valve on the other'modifications, it is evident that it can be readily applied to each.

From the modifications disclosed it is evident that the lamp may be constructed in varioiis ways. Hence I would have it understood that I do notconfine myself to the details herein shown and described, but consider myself at liberty to make such changes as fairly fall within the spirit and scope of my 3 invention. c

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. The combination with a main burner, and a commingling-tube, of an oil-supply pipe having a coiled vaporizing-section discharging into the commingling-tube, having a detachable connection with the supply-pipe, the

. specification in the said vaporizing-section being made of thin metal to permit of the initial vaporization of the oil therein by the heatfrom a match or torch, an auxiliary burner adjacent to the coiled vaporizing-section, and means for de-' fleeting a portion of the mixed air and vapor to the auxiliary burner.

2. The combinationrwith a main burner, a coiled vaporizing-section having a detachable connection to the supply-pipe and made of thin metal so that the initial vaporization may be started therein by the heat from a match or torch, and an auxiliary burner for continuing the vaporization of oil in the vaporizer, of a pipe located within the comminglingchamber for deflecting a portion of the mixed air and vapor to the auxiliary burner, and a valve for regulating the supply of air to the commingling-chamber.

3. The combination with a main burner, a commingling-chamber and a vaporizer exterior ofand wholly independent of the main burner-casing, and discharging into the commingling-tube, the said vaporizer being of thin metal so that the initial vaporization may be started therein by the heat from a match or torch and having'a detachable connection to the supply-pipe, of an auxiliary burner connected to receive vapor from the commingling-tube for continuing the vaporization of oil in the vaporizing-section.
